Keller Auditorium In Portland's spacious Keller Auditorium, audiences have enjoyed Broadway productions, ballet, operas, family events and much more. The Keller (originally known as the Civic Auditorium) was built in 1917. It was completely renovated in 1968. Throughout the years, it has been the 'workhorse' theater for the city of Portland, hosting many performing arts events each year. The building is home to the Portland Opera, The Oregon Ballet Theatre, and Oregon Children's Theatre. It also hosts many national acts and traveling Broadway shows. The concession stands (located on the main level and first balcony) offer fresh cookies, coffee, and other small fare. Full service bar locations are also open during most events. The Keller Auditorium Box Office on site is open 2 hours prior to performances for day-of-show sales and will-call tickets.
